This is a virtcontainers 1.0.8 import into Kata Containers runtime. virtcontainers is a Go library designed to manage hardware virtualized pods and containers. It is the core Clear Containers framework and will become the core Kata Containers framework, as discussed at https://github.com/kata-containers/runtime/issues/33 Some more more pointers: virtcontainers README, including some design and architecure notes: https://github.com/containers/virtcontainers/blob/master/README.md virtcontainers 1.0 API: https://github.com/containers/virtcontainers/blob/master/documentation/api/1.0/api.md Fixes #40 Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
